IKEA sensors for doors and windows, motion, water leaks

I've got a bunch of Xiaomi Aqara Zigbee water leak sensors and they have alerted me to leaks which could have caused a lot of damage if not caught right away. The siren on this Ikea one is a very obvious improvement and the price seems to be in line with the Xiaomi sensors that I currently use.

The motion sensor looks like a decent improvement on the existing one. I have to admit that I don't have the battery life issues that many people seem to have with the current model, but I've only got two of these sensors so maybe I got lucky.

The door sensor looks weird though. It seems a lot larger than the equivalent Xiaomi Aqara sensor. Maybe it uses AAA batteries instead of coin cells or something.

Generally speaking, I really like the Ikea Zigbee stuff. Everything I've got is well-supported by Zigbee2MQTT, including OTA updates. Most of my Ikea stuff has never even been paired to Ikea's hub.

I am more worried about US stuff with the whole PRISM thing and other three letter shenanigans.

Aditionally the comment you are replying to is a dongle to provide a single board computer (or a computer in general) with ZigBee conectivity.

Ideally you would run a trusthworthy open source OS and hub software.

Agreed, I would rather a foreign agency with no power or authority over me to have my personal data than a government that has the authority to wrongfully tax, investigate, jail, prosecute, and imprison me for that same data.

You should choose the devices that are the most secure, using the information you have available at the time.

Choosing a foreign government to spy on you rather than your own government isn't a clear choice. While a foreign government is less likely to be interested in you personally and likely less able to directly cause you harm, you also have less recourse against them than against your own government and their interests are less likely to be aligned with yours.

Additionally, your government may be able to co-opt the compromised devices anyway and would certainly have an incentive to do so.

I'd also question that a device that is by-design-compromised is otherwise secure from bad actors. It is difficult to imagine the incentive structure that would make that possible.

Finally, once this personal data has been harvested by either government, there is nothing to stop these governments or rogue elements within these governments from trading or sharing that data with your own government or other actors.

The problem is that the American government has shown time and time again that their interests are not in any way, shape, or form aligned with that of the public.

At this point, I’d trust a (likely) disinterested state actor over one that has been proven to be actively malicious.

I don't chose to be spied on by any government! But if I could chose only one, it would be an opposing country like China or Russia.

American businesses are forced to share our private data witn three letter agencies. Conversely, I can't imagine any leverage, money or lawful, that would cause a Chinese citizen living in China, with families in China, to be so stupid as to collaborate with the US government in any way, unless they wish for their families to be sent to labor camps.

My data is safer with the Chinese. I don't like it, but that's where we stand with our privacy.

My Sonoff Zigbee dongle presents itself on my Linux home server as a USB serial device (/dev/ttyUSB0) which gets forwarded to the zigbee2mqtt container which talks to it. Perhaps under a different host OS it might try to deploy something nefarious, but I'm not particularly concerned.

As other's mentioned, they communicate via serial to the host, this is not a device I'd be greatly concerned about as a threat.

Unless you took great care with sourcing your electronics then they're already packed with chips/parts from china.

If you _really_ want to you can use a nRF52840 (Nordic Semi is from Norway), or I think a few TI chips (USA), and use those as a gateway instead with home assistant (might need to add an extra library). Even then, both companies have manufacturing plants in china AFAIK so...

They have repeatedly proven to be a major privacy concern. Maybe security concern as well.

Thanks to Zigbee being a standard, you can use a Zigbee hub/adapter from any vendor you like. The Zigbee sensors themselves have no network connection and therefore noway to warrant privacy concerns really. There is no WiFi/Ethernet or internet involved with anything Xiaomi here.

I'm using a bunch of these Aquara Zigbee sensors with the open source Home Assistant software and hardware, they are for the most part fantastic.

I would take Zigbee home automation devices over crappy wifi ones any day of the week - its a vastly better protocol/methodology for hooking these sorts of devices up. Your home's lights functioning properly ideally should not depend on bulbs/switches being able to get an IP address etc (sigh)...

There were two things that pushed me to the SLZB-06:

* deCONZ was slow to get new device support and I had purchased some devices that weren't supported (Ikea STARKVIND) at the time. I think this has been improved since I last used it though.

* The SLZB-06 can be powered by PoE which gives it a lot more flexibility than anything connected by USB. Also, since it's not USB-connected, it's a lot easier to deal with (no need to figure out USB passthrough, etc).

How have you found the battery life to be on your Ikea zigbee devices? Mine have been generally disappointing. In the range of 3 months on the dimmers that are maybe 10 feet from the hub. Just got a couple of their newer dimmers, hoping those will be better. The pairing experience was certainly less painful.

Zigbee2mqtt is the bomb. ZHA can't hold a candle to it in terms of reliability, features and device support. The tiny increase in complexity is so worth it.

What exactly do you mean by a "dimmer"? Everything I have in my home that dims lights is mains-powered, so battery isn't a concern.

I have 45 Zigbee devices in my home, 33 of which are battery-powered. Those are door contact sensors, PIR motion sensors, climate sensors, and a few button remotes to control lighting. They're mostly from Sonoff and Aqara, with a few unbranded Aliexpress devices that identify themselves as TUYATEC, and a couple from Third Reality. In almost every case, the battery life has been extraordinarily good -- well over a year. The only exception is the Sonoff SNZB-04 contact sensor, which seems to need battery changes about every six months. Probably not coincidentally, it's the only sensor that uses CR2032 batteries, rather than AA or AAA. I would happily replace with a slightly larger sensor to get both longer battery life and less e-waste through the ability to use a standard rechargeable AA/AAA battery.

Ikea refers to several of their zigbee remotes as dimmers. This is the older one that I've had issues with:

This is the newer one: https://www.ikea.com/ca/en/p/rodret-wireless-dimmer-power-sw...

I have a few SmartThings motion sensors that are at 2-3 years battery life, though they use big lithium cells so that isn't surprising. A few sonoff temp/humidity sensors on coin cells seem to be heading for at least a year battery life as well. So far it's only the Ikea buttons that have issues.

You probably have battery issues because you are using SmartThings as the zigbee hub and it's polling the remote way too much.

I have switched to HomeAssistant with a Zigbee USB adaptor and there are no more battery issues.

SmartThings are aware of the issue but do not care enough to fix it.

I do use a few SmartThings branded zigbee sensors but not the hub. I'm using homeassistant with the sonoff efr32mg21 dongle.

I'm well aware of how terrible SmartThings the company is. I'd suffered through their inadequacies until April 2023 when they deleted my account during a failed backup purge. After 3 months of waiting on their support to unlock my hub I gave up and went to homeassistant.

Understood. This won't help you much, but I don't think I've ever had to change a remote's battery in the three years since I switched over to Zigbee. I assume their radios wake up only when the button is pressed, which is at most a few times a day, so the battery drain should be minimal. I use Home Assistant with a Sonoff Zigbee-USB coordinator, just as you do.

Those Ikea buttons look pretty ordinary, so I can't think of why they'd have such poor battery life. But they seem to be the only difference between our respective systems.

These are the buttons I use most: https://www.aliexpress.us/item/3256802252738635.html

I find that the battery life seems fine, but I haven't tracked it closely.

I have noticed a difference between Duracell coin cells purchased at Costco and Amazon Basics coin cells. The Amazon Basics ones didn't last long at all, the Duracells seem much better.

The newer dimmers (STYRBAR) use AAA cells instead of coin cells, so I'd expect them to last a lot longer.

I have a handful of Aqara motion sensors because some idiots on Youtube recommended them. They're shit compared to the Hue motion sensors though, and take 3+ seconds to respond while I look like an idiot waving my hands around and sometimes even need to take off my shirt and wave it like a flag to get the lights to turn on. The Hue motion sensors respond almost instantly in comparison.

All this low power electronics designed to run 3 years on a coin battery bothers me. If it's that low power why not get rid of the battery, slap a tiny solar panel (the kind they used on calculators in the 90s) and a supercapacitor, it should be able to power itself indefinitely on normal levels of room light, never go into deep sleep states, and can even turn the room lights on automatically if it needs more power.

The other one is sitting by the cat litter boxes and is used to trigger an automation involving an air cleaner. It senses the cats at a range of about 1.5m just fine.

I’m relatively sensitive to noises (analog clocks are a hard no-go because of their soft ticking; it’s infuriating trying to sleep somewhere that has them). But I barely hear our dryer when it’s running at night, and it’s just on the other side of our bedroom wall. As long as we aren’t doing a load with lots of hard buttons and things (which make a louder clinking sound when tumbling) the dryer is totally fine at night.

The washing machine, not so much. The water lines and spin cycle aren’t particularly loud, but they’re loud and distinct enough that it’s too loud for me at night.

23h45m

Unless you're running a pumped drain system, all of your drains must route to plumbing lower down.

If upper floors' floor drains route to lower floors before joining with other plumbing on the lower floor, that would prevent backups from rising to the upper floor drains (unless their particular pipe was clogged, which should be unusual in a residential floor drain). But you'll have this issue at least at the lowest level of the dwelling.

Basements are not common where I've lived, but where present in custom houses, they tend to be fully finished and plumbed and then they'd have floor drains too.

In some buildings elsewhere, I have seen a less finished basement, with only laundry and a slop sink... That slop sink may be where a backup from the lateral to the utility sewer (or septic system) would come out. But that's not a common look for a fully custom home.

Scoundreller

A lotta slop sinks are just washing machine drains. Lets your machine pump as quickly as it wants without needing to a separate high-flow drain. And buys you more litres of backflow before its a real problem. Tho some washing machines can pump up quite a few feet if needed.

Lived in an apartment where the front-loader managed to pump a sock into the high-flow drain where it got stuck. That was fun...

(Also had a front-loader break it's door seal, also a lot of fun...)

It's also a bit weird that washing machines don't come with water leak sensors but I guess manufacturers don't want to highlight the possibility of their products causing water damage.

A sensor can alert someone but doesn't stop the water. There are alternatives:

1) An electric valve directly at the tap that the machine actuates when it needs water. Usually comes with hose-in-hose to capture water from a ruptured line and detect and stop releasing water.

2) Quantity limiting devices to limit the quantity that can be used contiguously, and reset when the flow stops. Set to the maximum needed by the machine. Should there be any leak, the possible damage is limited. No electricity needed.

I’ve been wanting to jump into home automation for YEARS but the awful mix of incompatible products and standards coupled with the frequent deprecation of products which often require an online presence, and the outrageous prices being asked for these quite frankly beta products, kept me away. Once matter is standard I expect prices to drop and that’s when I think it’s safe to jump in.

Just use HomeAssistant and find ESPHome compatible hardware. It drastically simplifies everything and there are even vendors like CloudFree [1] that support it out of the box.

I've got several outdoor and indoor hydryponics systems set up that way and it's been a joy (except for the RaspberryPi SD card dying on me, which I've since replaced with a more reliable SSD based SBC)

HomeAssistant works, but I'm always surprised when it is praised on Hacker News given the preponderance here for rewriting every program in Rust.

Home Assistant is an unwieldy monolith where spitting out the components would give you so much more control. The side that receives the data works well, however. The quality of the plotting in it is substandard, as is the inbuilt data storage and access. Configuring via YAML is painful, especially when you want derived values (e.g. calculating absolute humidity from RH sensor readings. HomeAssistant comes with no way to clean up dirty data which is something you'll see on their forums that many people request, as cheap sensors are notorious for spurious readings.

It's easy and polished which is why I and I suspect others use it, but I wish there was a modular rewrite.

I agree with the monolith comment, but I am not sure the jab at Rust is warranted.

If we are rewriting HomeAssistant, let's do it in Rust :) Only half joking.

That said, I refuse to write automation in YAML. Logic doesn't really belong in YAML. Declarative stuff would be decent if all you did was to specify a desired end state and let it figure out how to get to that state. But triggers with the equivalent of 'if' conditions that run actions? Let me write the IF. It makes a big difference if you say "Lights should be on between X and Y" versus "condition: after: x before: y: action: turn on". Trivial cases are easy, but when you start combining them it becomes a nightmare.

I have done a lot with NodeRED but it is... strange. It does save me from writing YAML (I do enough of that on my day job), at the expense of being weird and not easy to debug.

As for plotting data, you can send that to Prometheus or InfluxDB and go from there.

I also wish there was an alternative. And more modular "plugins". And a "HA" option. As it is, I have a single raspberry Pi that, while backed up and could be replicated if needed, will go offline for updates and the like, not able to run any automation in the mean time.

It does work though.

As another sibling suggested you should seriously consider HomeAssistant here. A main selling point is it's ability to seamlessly integrate with an arbitrary mixture of Zigbee/ZWave/Matter/Kasa/<etc> devices under one management interface.

I've been running it for years, keeping up to date with the regular new versions, and haven't had any major complaints for basic use cases like: "I want to turn on <set of lights> when <arbitrary condition occurs> (e.g. sundown, certain sensors detect < X lux of light, wifi device is seen by access point based on its MAC). Super useful. Huge world of possibilities, limited only by your hardware and imagination.

Zigbee was the solution that solved these complaints for me. My home automation works 100% offline, thanks to Home Assistant + Zigbee.

Posted it in another comment here already, but this is my go-to resource to figure out compatibility: https://zigbee.blakadder.com/

And pretty much any zigbee device can be compatible with any gateway. In many cases it's just whether someone has taken the time to wire it up in the software or not.

Working on it, expect it after summer. Zigbee+ble+thread+wifi, but currently only sold in EU and for now only supports our own zigbee devices. Search for Ferguson Digital FS2SH. This hub already has ZB, we will add thread via dongle + firmware update. We plan to add matter support to all devices which we can control (slowly adding more, we want them all, but are limited by number of programmers). It's also a little HN worthy, because we plan to use standard nrf dongle and hub will program it on the fly after insertion (for other protocols in future), so you could buy it cheaply yourself. Plus, it has unhindered openwrt root console on easily accessible header inside (will void warrranty though).

Same here. I also find myself peeved at the article author, who for some reason decided to spend half a paragraph essentially parroting the company's PR over just how justified this delay is, despite earlier mentioning that they promised Matter support over a year ago.

Ikea ... has “decided to delay this functionality” and will provide an update “when it’s time.” The ongoing delay is understandable given that Ikea’s products already integrate well with other platforms, and the company is focused on keeping things as simple as possible for anyone who delves into the smart home on a whim while shopping for a new bookcase. And when you consider the hurdles required to get everything running on Matter networks during this period of transition, Ikea’s delay is more than justified.

insane home automation tech prices

And yet some comments are complaining that it’s more expensive than a Tuya-based solution or whatever. I think this is at the heart of the problem: people want the longevity and cost of a dumb-home product, but the value of these things is rooted in software. Cognitive dissonance ensues—“you want me to pay a subscription for a door lock?” At least here, IKEA is allowing point-to-point communication that could eliminate moving targets of other companies’ software.

The new hub is different, and does not work with the old Ikea system.

At the $10 price point? Z-wave stuff always seems to cost more, and my understanding is that is largely due to the requirements for compatibility and testing per Z-wave alliance. I'd be shocked if this same thing could even be made at reasonable margins for $10.

The flip side to this, is Zigbee stuff always has a lot of little quirks, problems, or bugs. There's literally an entire module/database for ZHA (Zigbee Home Assistant addon) called ZHA Quirks that's designed to work around all the little issues with various devices.

I don't agree. I was an early adopter and I still have some Z-Wave devices, but I won't miss them when they're gone. Pairing is a hassle, unpairing just as bad or worse, and licensing costs mean the devices themselves are always more expensive. My USB dongle for Home Assistant supports both Z-Wave and Zigbee, and as I add new devices and upgrade old ones over time, I'm not buying any new Z-Wave.

At least for the water leak scenario, the best approach is to put a drain pan under any appliances that could leak (laundry machines, dishwashers, water heaters). The drain pan should itself drain to a pipe.

Ideally, a water leak sensor should be used help to catch a slowly failing appliance so you can repair/replace it before it does major damage, not preventing it from doing damage in the first place due to a sudden major leak.

NoMoreNicksLeft

Of all the leaks I've had these past 10 years, only two have been appliances, and one was high pressure (water heater). The other as negligible. Both of those didn't need sensors.... they were obvious, and quickly.

The leaks that haunt me though... several under the house in the crawl space. Copper pipe pinholes, caused I don't know how much damage (including several ruined water heater elements, maybe even causing the water heater to fail prematurely). Ruined floors. Until they got bad enough that we had no hot water (which was about the time the floor started warping), there doesn't seem to be anyway that we might have noticed. The water bill wasn't unusually high, or maybe it just frog-boiled its way up where we couldn't. There were several more copper pinholes, but they were noticed as muddy places in the crawlspace while fixing the first, or just spidey-sensed. I am also very nearly too fat to crawl under the house, let alone do emergency plumbing while there.

Another incident involved a squirrel. The idiot owners of this house (before us, not the current idiot owners) decided that the easiest place to put new plumbing was in the ceiling (maybe they were too fat too?). Our attic had a new uninvited guest, and apparently PEX piping is very tasty. Or appears that way, the squirrel lost his appetite after biting enough of a hole that there was a leak from above. This leak though, despite the location which should have made it almost instantly obvious, happens almost within 5 minutes of a torrential downpour that lasted better than an hour. That, plus my unwillingness to believe the previous owners had routed plumbing above everyone's heads, meant we didn't get that taken care of quite as quickly as we might have.

My lessons from this, I think, are:

1. We might have caught the crawlspace leaks quickly if there were a humidity sensor (is that how the leak sensors work?) down there, and we could have compared to baseline. That is, if spraying water didn't just fry them immediately.

2. The ceiling leak probably couldn't have been detected very early, given the coincidence with the rain and how it would have raised humidity. Possibly if we had a water pressure sensor, that would have picked it up as a drop, despite there being no faucets running.

Plumbing sucks. Houses build 50 years ago assumed that it could never fail often enough to make it easily accessible. My next house will take into consideration squirrel mitigation concerns.

My water utility just switched me to a smart meter, and now I can sign up for leak alerts.

They must be doing it by analyzing the usage data somehow. Maybe they alert when there are too many hourly time intervals that all have almost the same usage (since a leak would be continuous and constant). Or maybe if it has been too long since they've seen an hour with zero usage. Something like that.

Anyway, it should be able to catch leaks anywhere in the house.

Humidity is unlikely to help: I have temperature/humidify BLE sensors all through my house and humidity varies wildly. You'd have to do some sort of calibrated long-term machine learning thing to maybe pull out the data.

Much better would simply be digital water meter tracking (which is still amazingly hard to actually do) since when all the taps are off, if you still have substantial water use then you probably have a leak (I would really love a decently accurate ESP-based water meter with like, Sharkbite fittings on it so I could check the water flow out of all my taps or something).

The best solution is a water shut off valve [0] and a bunch of cheap zigbee water sensors.

Drain pans won't handle a catastrophic failure. I installed this in our house to protect against pipe failure. We had the old grey poly-b pipe (since replaced) that was used in the late 90s.

You can DIY this if you are handy with soldering copper pipes, or get a plumber to install it for a couple hundred bucks.

Apparently water damage claims cost exceeds fire.

We had a whole-home drain backup some time ago that would have been CONSIDERABLY less damaging if we had been alerted to the backup when it occurred. Instead, nobody was inside and a draining laundry machine hit the clog and pushed black water throughout most of the first floor.

Knowing that this was happening would not have likely saved the bathroom, or the laundry room, but it might have saved the kitchen.

Point is: for water leak scenarios you should think about both clean water coming from inlets as well as clogs in your outlets.. I should get a couple of these to place behind my lowest toilets, where the water came up last time

What’s the practical indoor range like on these? I’ve found the useful range of Z-Wave devices to be embarrassingly poor, and I think it’s largely because, in the US market, some kind of regulatory issue limits transmit power to 0dBm or maybe even less. (Z-wave LR is much higher, but it’s not ready for prime time.). ZigBee apparently allows up to 30dBm, which should more than make up for the less favorable frequency range.

Does anyone have any experience with how far it can reach through typical indoor construction?

I wasn't aware of the purported regulatory radio limits on power, but I can report anecdotally that I found a huge jump in usability/signal strength/ownership satisfaction when I started replacing my old ZWave 1 stuff with the 500-series or above hardware (ZWave "Plus" is the name for these sometimes).

This "LR" stuff you mention is what I think some are calling the Z-Wave 800 series. It more than doubles the radio range of the 500 series stuff and greatly reduces power draw for battery devices. However, I have 500 and 700 series sensors that only need a battery change once every ~2 years or so. I don't find that to be too much, and the signal strength has been no problem for me in an old brick house. I do have a handful of powered zwave devices around though, and these act automatically as repeaters for the other devices in the mesh.

I have a mix of 700 and 800 series Z-wave gear, and I find it borderline useless — a mesh hop struggles to reach one room over.

LR is a rather different thing — slightly different frequency, very different topology, and it requires explicit controller software support. As far as I can tell, most or all 800 series hardware supports LR, 700 might with appropriate firmware, and earlier chips do not. node-zwave-js does not yet support LR, but someone seems to be working on it (slowly).

Hopping is widely advertised, but in practice is not really used as much as you might think.

With external antennas most of your devices (unless you have a really large home) will connect directly to the hub. And even the ones that hop will go through walls better with the Z-wave frequency - this especially helps if you have lath and plaster in your home, or metal electrical boxes for the switches/outlets.

The z-wave frequency in other countries is basically the same - they are all in the upper 800's, lower 900's MHz. https://www.silabs.com/wireless/z-wave/global-regions

I use the Ikea outlets and Hue bulbs.

An important part of my setup is that all the switches in my house still work, and won't actually cut power to the bulbs. There are decent options available to add a Zigbee (or wifi) dimmer/relay/remote behind an existing light switch, which is also great for controlling lights that aren't Zigbee and/or multiple devices simultaneously.

This has the added benefit that the stuff it's controlling doesn't have to be on the same circuit, and "rewiring" a light switch is done very quickly in software instead of physically rewiring.

The Hue wall switch dongle creates a "fake" switch, the bulb is powered 100% of the time, the on/off on the wall switch just tells the hub to tell the bulb to switch on/off.

You'll find that the failure mode is the opposite of what you're worried about. If you rip out your hub and flip your main fuse off/on you'll find yourself in the blinding light, not the dark. When the bulbs are powered on and can't reach the hub they default to 100%.

Yes, but only if the light it's controlling isn't zigbee. If the light itself is Zigbee I never want that device offline, because it's frustrating to have inconsistent state when controlling it through the various ways we're used to.

A core part of my home automation is that it fails gracefully.

Same. Most of my light switches have a Zigbee relay (or Shelly) behind them controlling non-Zigbee lights, and I can flip the physical switch (which still works if/when LAN or Zigbee is down) or use remotes/voice/automation through HomeAssistant.

I do have a couple light switches that I've hard-wired to be always-on and the switch itself relies on HA to function, but that's only because they were hooked up to a single outlet and became much more useful as a "remote" rather than a hardwired 110v toggle.

You can do this without connected devices, depending on the configuration of your bathroom!

You can get night lights that plug into an outlet, turn on when it’s dark, and brighten when they sense motion. I have some Casper ones (that also let you disable the motion sensing): https://www.amazon.com/Casper-Sleep-Glow-Night-Light/dp/B09L...

You can also configure you bathroom with multiple lights where some are connected to dumb motion sensors. e.g. Panasonic makes bathroom fans with a primary light and a night light - you can connect the night light to something like a Lutron Maestro motion sensor that goes in the wall where your light switches are. (Or if you want to get fancy, you can get a ceiling-mounted motion sensor and a radio-capable Maestro switch/dimmer that can communicate only locally with the motion sensor.)

It’s matter support with a hub. They promise matter support with an OTA. Notably none of their marketing copy or the box says matter support.

Support of the new smart home standard, Matter, is also planned for the FP2, and will be added to the device via a subsequent OTA update

The question to me is: are they actually good? I've bought into the Z-Wave ecosystem, and by and large all the Z-Wave door/window sensors available on Amazon have bad reviews. They have issues maintaining a connection to the network, they drop events, have terrible battery life, etc. The Zigbee sensors on Amazon seem a bit better, but still.

I'd seriously consider getting a Zigbee USB stick if I knew these function well and have good battery life. I just bought several $40 Z-Wave door/window sensors that got decent reviews, but at 4x the $10 IKEA price, I'm not going to be buying many of them.

I've got a single motion sensor, and all light bulbs in the house done with IKEA's TRADFRI bulbs, all bought nearly a year ago. The stack is a zigbee USB stick, Zigbee2MQTT, mosquitto and HA.

The lights are decent, I've had 2 fail so far, but both were on the same spot so I suspect something's wrong there.

The motion sensor has been pretty reliable, still working with no signs of failure. Delays or "dropped" events (the light not turning on) have been very rare and most likely a result of the ancient server I have than the motion sensor itself.

Heads up: you can bind two ZigBee devices directly. So a sensor can trigger a light without requiring a hub to even be on. It can even work across the mesh network.

You'll have a good experience with zigbee if you have a solid base layer of lights or smart outlets. Mains-powered devices act as repeaters in zigbee networks. Without enough repeaters, it might be tricky to place a distant contact sensor and have it behave reliably.

Like other commentators, I have both z-wave and zigbee networks running. Z-wave has better standalone penetration (lower frequency), but if I were to build from the ground up again I would go all-in on zigbee. One of the few reasons I have a z-wave network at all is a smart lock, but these days there are more zigbee offerings there.

All lights in my house are hue bulbs, using a deconz setup controlled by home assistant. My aqara motion/contact sensors get ~2 years of battery life.

cyberax

Z-Wave is less power-efficient in real life. And you can say that because up until recently there had been exactly ONE chip that implemented the Z-Wave stack.

You could open any Z-Wave device and find exactly the same chip, usually on a daughterboard. It worked well enough on mains power, but battery life sucked. This started to change several years ago, but battery-powered devices are still hit-and-miss.

ZigBee has always had a robust infrastructure of manufacturers, who actually compete on quality and price.

I have large zwave AND zigbee networks. They're very equivalent. I find that the hub is the important factor for ZWave where as each device is important for Zigbee.

Since ZWave is licensed and controlled, I've only had issues where (actual example) a siren supported playing multiple tones but the hub didn't support that particular feature directly.

My experience with Zigbee is slightly different. Being an open standard there are lots of cheap choices however it also means that because there is no licensing to use it, not all of the devices branded "zigbee" are fully compatible with each other. My personal experience leans more towards "Pair the device and cross my fingers that it is compatible". If it's not, nothing works.

Otherwise; They all use the same basic tech (PIR, Resistance for water sensing, magnets and reed switches for door/window open closed) so it really comes down to implementation.

That sounds like it could be a lazer/ir gate in the lock hole to detect it being in the way, but the custom job to jam it into the frame side of the lock might be quite delicate work if it's wood, or even worse if the frame is some prefab unit. Another DYI alternative would be to open the lock and see if you can stick a magnet somewhere in the mechanism where it won't impede movement and that has enough space for the solenoid. Neither of these are what I'd call complex, but also wouldnt call them easy to pull off. I would have to assume that somewhere out there someone is selling this already made.

I've got a Moen Flo water sensor I really love. It was something like $25 with no monthly fee, has a surprisingly good app (also measures temp + humidity) and can even be paired with a valve that automatically turns off the water in the case of a detected leak.

What I like best about it is it can not only set off a siren and notify me in the app, it'll also send a text message and even call my phone which is huge because if I have a water leak I want to know no matter what.

The Moen Flo valve does more than that! Every night it will shutoff your water and observe the pressure. If the pressure drops when the valve is off it will alert you of a leak. They're a bit costly at ~400 bucks, but water damage is so expensive it's worth it. I have one and it's great.

Insurance companies will give you a small discount if you have one installed as well.

My only smart home devices are old "Philips" Wiz Wi-Fi bulbs. They were cheap and I could set them up to change color temperature and brightness to help me fall asleep and wake up on time - it really seems to help. But they were hard to pair and every few months they'll disconnect from WiFi and need re-pairing. The proprietary app is somewhat annoying and they released a new V2 app which is more annoying and (from what I can tell) doesn't have any widgets or siri shortcuts so I need to launch the app every time I want to turn the lights on or off. I'm sure some newer WiFi bulbs work better but by nature they have to use the cheapest possible WiFi hardware and I'm wary of them clogging up my airwaves, forcing low PHY rates, and being incompatible with newer WiFi technologies like U-APSD.

My new LG TV has a built-in Matter Thread hub, so Thread sounded perfect. No proprietary apps needed, compatible with everything. Just point your phone at the QR code to pair. Fully local, low-latency mesh networking. But it's new so the devices are more expensive and there's a really limited selection. The early-adopters of Thread experienced some reliability issues but those have been fixed (?) I can't find much info about LG's Thread hub implementation but it seems like I'd need to add new devices through LG's app and I'm wary about how LG's integrations tend to be unreliable and how they try to turn open standards into de-facto lock-in experiences.

Zigbee and Z-Wave felt like old news to me. The last vestiges of the semi-open proprietary home automation market for people who are already locked in and willing to pay $60 for a light switch. I really don't want to have to buy a hub. I also had some bad experiences with some very expensive ZigBee wireless relay modules I used in a product at work. I think this thread is causing me to rethink ZigBee. Cheap, open, compatible. I wanted to get a low-power always-on server to host the Grafana/MQTT for my Open Airgradient air sensor anyway, so I may as well plug a Zigbee dongle in and run Home Assistant. Might get a Home Assistant Green or Yellow.

You'd need something with brains. Detecting the water is easy, but you want something that can check local weather and correlate with that. Ideally a rain sensor at the same location. I could do this with my Tempest and Home Assistant, I'm sure. But... I've never had a pool equipment leak that bothered me. All my equipment is outside the house and a leak isn't a top concern. if it were in the garage, I'd be more inclined to put a sensor there, but then rain correlation wouldn't be a problem.

They must have some weird research dept there. The first color changing LED strips I found for a reasonable price also came from IKEA. It was several years before anyone matched the price point.

It's like IKEA meets high-tech without breaking the bank. Comparing with Xiaomi's offerings, IKEA's got some neat features, but hey, there's that size difference. Maybe IKEA's going for durability over discretion? And, amidst the tech showdown, let's not forget about privacy – a big shoutout to those mindful of what's phoning home. In the world of smart sensors, it's all about finding that sweet spot between functionality, price, and trust.

Very happy with the news! I have about 40-45 zigbee devices in the home - 20ish bulbs and switches connected to the Hue gateway (soon to be abandoned thanks to Philips' new account requirements.... screw them, but that's another story), the rest mostly sensors connected to my zigbee2mqtt/Homeassistant setup.

I am very happy with the Aqara devices but they're relatively expensive. The sonoff stuff is garbage (sometimes needs re-association with the controller for no clear reason, and always when I replace the batteries.. which is often), the IKEA stuff (switches and motion sensors mostly) has by far the best price/performance ratio and is quite reliable, but the battery life is quite disappointing on all of them.

The new motion sensor having 3 AAA batteries (rather than 2xCR2032) should ensure a rather less disappointing battery life!
